Over the years I've spun up countless rails apps, most of which don't amount to much. I usually just go with whatever the latest Rails version is. Recently though, I was looking to try out the new <a href="https://weblog.rubyonrails.org/2021/9/17/this-week-in-rails-rails-7-alpha-released/">Rails 7 alpha release</a> and see how I felt about using it with esbuild. Most articles out there show how to upgrade an existing Rails app to using a alpha release. I wanted this to be a fresh project. 
After a little bit of digging I found exactly what I needed.
<pre><code>gem install rails -v '7.0.0.alpha2' -V --no-document
</code></pre>
This installs the rails alpha, to double check that it installed correctly, you can run:
<pre><code>gem list rails --local
</code></pre>
You should see the new version returned in the results. Once I'd verifed that it was correctly installed, I ran the <code>rails new</code> command making sure to include the specific Rails version. 
<pre><code>rails _7.0.0.alpha2_ new MYAPP
</code></pre>
There you go, Rails 7 is now ready to go. If you're looking to use Rails 7 in conjuction with webpack or esbuild, I recommend reading through <a href="https://www.colby.so/posts/live-reloading-with-esbuild-and-rails">this article</a>, which does a really thorough job of explaining how to do that.
